Le télescope est un instrument destiné à observer les astres. Le modèle mis au point par Newton est constitué d'un miroir primaire sphérique concave
Le télescope de Newton se compose de différents instruments optiques : miroir plan lentille convergente et miroir parabolique. La modélisation du télescope
Un télescope de Newton comprend trois systèmes optiques: - un miroir primaire ?: miroir parabolique de grande distance focale et de grand diamètre pour capter

might be presumed that the drawing and description of the reflecting telescope would have been given by Newton to Nikolaus Bernoulli during the latter's visit to London in 1712 Nikolaus Bernoulli had at least three meetings with Newton as may be seen from a letter written by Abraham de Moivre to Nikolaus's uncle the mathematician
Further Newton had already tried to explain his new invention for telescopes to Collins at their first meetings in London during a visit of Newton to the capital about the end of November 1669 For Collins afterwards wrote to his friend the Scots mathematician James Gregory (1638-75; F R S 1668):
Newtonian reflecting telescope can be designed to perform more efficiently than any other type of optical system if one is careful to follow the laws of nature One must have optics made from precision Pyrex or a similar material and figured to a high quality
The Newtonian unit became the first reflecting telescope. The technology improved component quality. The manufacturers have access to better and more durable parts. The actual design of reflection units didn’t change much. You’ll still notice the original Newton’s construction to secure an impressive image quality.
Newton’s simple telescope design is still used today, by both backyard astronomers and NASA scientists. A drawing of Sir Isaac Newton dispersing light with a glass prism. The next time you look up at a rainbow in the sky, you can thank Newton for helping us first understand and identify its seven colors.
Newton’s telescope solved these problems. A mirror doesn’t pass light through it. It simply bounces all the light off the surface. There is no chromatic aberration at all. And because you only need to bounce light off the surface you can place the whole mirror on a supporting structure or base which takes a lot of the weight off the mirror.
